Method for tracking target by linking wide-angle camera and telephoto camera with double holders

The invention discloses a method for tracking a target by linking a wide-angle camera and a telephoto camera with double holders. The method comprises the following steps of: enabling the wide-angle camera to carry out the target recognition, and marking a to-be-tracked target, enabling the telephoto camera to be aligned with the wide-angle camera, so that the Z axis of the coordinate system wherethe telephoto camera is located coincides with the optical center connecting line of the two cameras, rotating the telephoto camera, and searching a to-be-tracked target marked in the wide-angle camera, and enabling the telephoto camera to track the target and performing zooming to check the target. The method disclosed by the invention can automatically identify the target, automatically track the target and improve the detection speed and efficiency, and the performance is reliable and stable. 本发明公开了一种广角相机与长焦相机联动双云台跟踪目标的方法，包括如下步骤：广角相机进行目标识别，并对待跟踪目标进行标记；长焦相机对准广角相机，使长焦相机所在坐标系的Z轴与两相机的光心连线重合；转动长焦相机，搜寻广角相机内标记的待跟踪目标；长焦相机
